roll paper at 100×100 dots/inch at up to three inches per second.
From IEEE Computer, November 1973:
ELECTROSTATIC PLOTTER (p. 38). "A high-speed electrostatic printer/plotter
that produces computer-generated graphics on 22-inch wide paper was
announced today by Data Systems Division of Gould, Inc. The Gould 5100
plots graphic material at up to three inches per second and has a resolution
of 100 dots/inch vertically and horizontally. With the addition of a 96
ASCII upper and lower case character set, the Gould 5100 can print full
alphanumerics at 264 characters per line and 1200 lines per minute. The
Gould 5100 accepts 400 feet of coated paper rolled on a 3-inch internal
diameter core. Traveling through the unit, the paper becomes electrically
charged and fluid toned, emerging dry from the machine. The toner adheres to
the charged areas, thus creating images."
